'14 35i, new to me as of 11/22, currently with 37k. Issue free during its first northern New England winter, up until a few days ago. On a longer interstate drive (5 hrs) got a low coolant warning about 2/3 through the trip. Added coolant the next day and ran w/ hood open and basically had coolant pouring out of the bottom port of the expansion tank (could have been leaking from above and running down the tank). Could see the dried blue drops from spray around adjacent parts. Would top off coolant (1-2 L) and 25 min of running later the light would ping again - needing another liter plus to refill. Shop replaced the expansion tank and did a pressure test. I asked them to be sure no other leaks within the cooling system and they said the pressure test revealed no other leaks. So, that's where things stand now. Reading how similar others' experiences have been, I am readying myself for this being an extended struggle. For those with greater technical or experiential knowledge: What causes an expansion tank to fail suddenly? Back pressure? I am no expert, but it does not seem like a strained part with a finite lifespan. If the expansion tank failure is essentially the result of latent design flaws within the whole cooling system, what is the best way stay ahead of any possible/likely future failures? Constant monitoring of coolant levels? Using OBD to check in codes/coolant temps frequently? In the event I need to replace the radiator, I am inclined to opt for the CSF 7046 - as you said, peace of mind. But living in a colder climate would need to wrestle with some of the noted temperature issues (sub 20f is fairly standard where I am between December-February). Curious if/how folks deal with that. Appreciate any shared thoughts. |
